## 8.3 Security and privacy, in short

- **Tools run sealed**: in a frame on another domain, without network access. A tool can't read your account, can't call any server, and only reaches its data through LeavenIT, which checks your rights each time.
- **Who sees what**: your personal data is yours; a shared folder's data is visible to its members; a folder with separate data only to the people chosen. Tools on the Showcase are public; their users' data isn't.
- **Where data lives**: by default with LeavenIT's providers (Supabase, in Europe). With **your own storage**, a data area's tables live in your bucket, at the provider and in the country you chose; you are then responsible for that place.
- **Keys**: LeavenIT keeps your storage key encrypted and never shows it again. A Runner holds no storage key; LeavenIT keeps only a fingerprint of its token.
- **Emails** are sent from `noreply@leavenit.com`. LeavenIT never asks for your password by email.
